Aye, that works. You've arrived and you have a hobble where your dwarves live while you attempt to carve out the mountains to create a city.

For further reference, the first dwarven player, [@kaiserauto], is still constructing his city. It's taking 7 turns in total. So I'm not gonna let you start off with the city already built I'm afraid, but you can jump in with having started construction already.
